Employee lifecycle change orchestration for ADP shops

The moment an HR manager needs to rehire a former employee, or move someone from part-time to full-time, or bring someone back from leave, they discover the hard way that completing the change correctly requires hitting five or six separate screens in a specific order — and one wrong step wipes benefits history, creates a duplicate record, or sends bad status data to their 401k vendor. This is not a bug anyone is racing to fix: ADP's incentive is to keep HR admins deeply embedded in its own UI, and modularizing the update flow in a way that works across all their product lines (Workforce Now, TotalSource, Comprehensive Services) would require cross-team coordination ADP has little reason to prioritize.

What users actually describe is a coordination problem, not a data problem: the data exists, but triggering a 'rehire' or 'status change' event requires a human to remember every downstream module that needs updating — benefits, payroll, seniority dates, sick and vacation accruals, reporting structure — and visit each one separately. There's no orchestration layer. Miss one, and the error surfaces weeks later when payroll runs or a benefits enrollment breaks.

Without something to manage this, HR admins at mid-sized companies (100–500 employees) keep personal checklists in Google Docs or Excel to track which screens to hit for each event type. That costs roughly 30–60 minutes per lifecycle event and creates a meaningful error rate. At a company running 20+ lifecycle events a month during growth or seasonal hiring, that's a real and recurring labor cost — and the downstream corrections (fixing a 401k vendor data mismatch, re-processing a benefits enrollment) cost far more.

This gap persists partly because the buyer (the HR director or VP of HR) is not the daily user (the HR coordinator or benefits admin), so the friction gets absorbed quietly rather than escalated into a vendor complaint that gets prioritized.

What to build

Build a workflow engine that connects to ADP via its existing API, maps common employee lifecycle events (rehire, status change, leave return, part-to-full transition) to every affected field across modules, and presents a single checklist UI where the admin confirms each update in sequence — with rollback warnings if a step would overwrite existing benefits or seniority history.

Where to start

Start specifically with the rehire workflow, because it has the most documented downstream damage (benefits history wipe, 401k vendor mismatch) and HR teams can immediately articulate the cost — making it the easiest event to build a clear ROI case around for a first sale.

The hard part

ADP's API coverage of all the relevant modules (benefits, payroll, org structure) is uneven and subject to rate limits, so early on you'll hit cases where a step in the checklist can't be automated and has to be a 'go do this manually' instruction — which undercuts the value proposition and requires careful UX to avoid looking broken.

How it makes money

Monthly per-seat subscription charged to HR admin seats (not employee headcount), with a higher tier that unlocks custom event templates for industry-specific lifecycle events like seasonal rehires or contractor-to-employee conversions.
